The subsurface process is composed of a series of complex geologic processes, hence, it's modeling can only best be undertaken by a team of professionals from each of the relevant majors.
Modeling the earth's interior requires the expertise of geophysicsts in using geophysical techniques to obtain subsurface readings at various depths, seismologist obtains and interpretes arrival <em>times of seismic waves</em>, petrophysicst evaluates subsurface properties using log data and so on.
Therefore, the complexity of the subsurface makes it imperative that professionals collaborate in other to come up with an accurate model.

Answer:
pH = 4.7
Explanation:
The pH is a measurement of acidity using the concentration of hydrogen ions (H⁺) in a solution. Therefore, before you can find the pH, you need to determine the concentration (M) of H⁺ in the solution. This can be done by multiplying the molarity of the solution by the amount of H⁺ in the solution.
1 mole H₂SO₄ = 2 moles H⁺ and 1 mole SO₄⁻
1.0 x 10⁻⁵ M H₂SO₄ 2 moles H⁺
----------------------------- x ---------------------- = 2.0 x 10⁻⁵ M H⁺
1 mole H₂SO₄
To find the pH, you need to use the following equation:
pH = -log[H⁺]
Since you calculated the hydrogen concentration ([H⁺]) in the previous step, you can plug it into the equation and solve.
pH = -log[H⁺]
pH = -log[2.0 x 10⁻⁵]
pH = 4.7
